SPECIFICATION forming part of Letters Patent No. 273,226, dated February 27, 1883.

Application led October 31, 1882. (No model.)

To all whom it 'may concern Be it known that I, PETER T. OOFFIELD, of

Springfield, county of Clarke, State of Ohio,

have invented a new and useful Improvement in Wind-Engines, of which the following is a specification.

In the accompanying drawings, Figure 1 is a vertical sectional elevation, representing my improvements applied to awind-engine. Fig.

1o 2 is a partial sectional elevation of a modified construction of the same invention. Fig. 3 is a plan view ot' said modification, and Fig. 4 is a partial sectional elevation of second modification. Fig. 5 is a sectional View of still anx other moditication, hereinafter described.

The present invention relates to windmills of the type known as geared mills, and has for its object the obviating of difficulties arising from the shifting` ofthe wind-wheel when zo opposed by the work to he performed. It is a common thing for the wind-wheel of a geared mill, when opposed by work to be done, to move around from a point that is suitable to the line of direction of the wind to a point that is not z5 so suitable, and thereby lessen, if not completely destroy, its usefulness. n

The invention consists in an extension forming part of and depending from the mill-cap. and carrying at or near its terminus a system 3o of balanced gear-wheels that prevent the independent turning of the mill-cap.

To enable others skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe its construction and operation.

The wind-wheel a is mounted upon a shaft, a,that runs in journals formed in the cap fn. A bevel-gear wheel, b, secured to the shaft c', meshes into a bevel-wheel, c, thatissecured to 4o the shaft d. The shaft d passes through the Vertical extension of the cap n. and rests in a cup, d', although it is not essential for the aforesaid shaft to rest in a cup, d', as it is ob- Vious that the collar Z may have radial arms extending to the derriek n, which would anlar, m, and the wheel f gears into a double 5o bevel-wheel, g, that runs loosely on the extension of cap n. A collar, Z, fast tothe aforol said extension, holds the gear to its work. The wheel g transmits motion to a bevel-wheel, 7L, fast upon the shaft t', from which power may be obtained for any purpose desired. 4The mill-cap 'n turns in a bearing, n', that rests on the derrick u, and a vane, p, is attached to said cap for the purpose-of turning the windwheel into the best position for work.

` In Figs. 2 and 3, I have shown a modification, wherein the arrangement of the cap n and gears c b are identical with those above described, butl in which I substitute spurwheelsrs tfor bevel-gear cfg, and acollar,f, for the collar m. 1 furnish this collar f with studs q q', upon which the gear'wheels s t revolve; but in place of the wheel hand shaft t',

I use an internal gear-wheel, h', and ashaft, i.

In Fig. 4,1 illustrate another modification of 7o this invention, in which the bevel-wheels c g' f" h" take the place of the bevel-wheels e f g h, and the boxf" takes the place ofthe collars im, all of which will be easily understood from an examination of the drawings.

If the mill-capot simply supported the windwheel a and vanep, and was otherwise free to rotate around the shaft cl as a center, it is plain to see that the bevelwheel b, when opposed by the work to be performed, could swing around the wheel c in place of turning it, which it cannot do with my improved construction.

In Fig. 5 the head-gear on the windwheel shaft engages a bevel-gear loose on the shaft d, and this engages a gear,f, which meshes with a third bevel-gear, n'", fixed on shaft d. During` the rotation of the shaft upon which the wind-wheel is mounted the shaft d, Fig. l, is rotated through the medium of the bevelgearsb and c. The bevel-gear e, lixed upon shalt d, carries the loose gear fto turn the loose double bevel-gear g, and this in turn drives the gear It upon shaft If, now, the cap orturn-tablcn,withits'lowerextension,through which the hnft passes, is turned, its collar m will be turned with it, and the loose gearf, carried by said collar, will roll upon the bevelgears e and g. By such means all twisting of the shaft will be avoided. When the gears are arranged as in Figs. 2 and 3, the shaft carrying bevel-gear c and driven by gear b will, during its rotation, cause its iixed gear r to turn the loose gears s and t, which in turn cause the revolution of the internally-toothed wheel h', which is txed on shaft 'i'. Under such arrangement, when the cap or turn-table and its extension are turned, the gears s and t, loosely mounted on studs on collarf, roll on the internal line of teeth ot' wheel h.

In Fig. 4 the Wheels e' and e are loosely mounted on a spindle on the yoke or collarf", which is fitted on the lower extension of the cap a, the gear g' turning with a shaft, d, driven,

1 as in Fig. 1, and thegear l1, turning with a shaft, t'. Hence when the collarfl is turned the gears e and f roll on the gears g and h.

In Fig. 5the gear b, fixed on shaft a', rotates the loose gear e, which in turn rotates a loose gear, f", and this latter gear causes the gear through the medium ot' gear-wheels, substantially as described, and which is provided with a fixed gear meshing with a loose gear, which in turn meshes with another loose gear engaging a gear xed on the shaft for operating the machine to be driven, substantially as described.

2. The combination, with the shaft d, carrying a fixed gear, e, of the collar m, carrying a loose gear and connected with the turn-table, thedouble bevel-gearg, and the gear 71 mounted on shaft t', said members being combined and arranged substantially as described.

3. rJlhe combination, With the Wind-Wheelshaft supported in bearings on the turn-table,

ofthe shaft d, passing through an extension 'Y PETER T. COFFIE'LD.
